N64 was my first console as a kid that was totally mine (I'm 32). My family had an SNES but I don't remember playing it much. Then I got heavy into EverQuest as a teen and even skipped getting the GameCube. I've played most the ones on DS/3DS/Wii and PS4. Still need to play the FF9 port on PS4 that came out recently.
My first FF game was actually 11 - and I played it pretty heavily and loved the lore and story and it got me into looking into the others.
So I've played 1, 2 (didn't finish, bad game), 3 (DS remake, meh), 4 (DS remake, great), 7 (didn't finish, was using a borrowed PS1 one summer - looking forward to the remaster), 11, 12, 14, and 15.
I'll probably never play 5 or 13 and it's spinoffs as they are ranked in the trash tier of most lists.
